Conclusions
The addition of 0.08–0.20% V changes the fine structure of cast steel 45FL after quenching and tempering as compared with steel 45L without vanadium — the mosaic block size decreases and microdistortions increase. The effect of vanadium on the intragranular structure of the steels investigated is greatest at elevated tempering temperatures (550–600°).
